AFAICT the code starts the JVM using an OS process.
It also makes assumptions about the classpath separator character that may
not apply to all OSes.
There may be other such assumptions. EXEC should already deal with all of
these.
I still think this belongs in EXEC rather than LANG.
It might make a useful enhancement to EXEC?---
